February ’21 rFactor 2 GT3 BoP Update Available

Studio 397 today deployed an update to all their newer GT3 cars. Based on the release notes it seems like this was a huge undertaking, and should make the GT3 cars much more competitive. From their release post:

Here at Studio 397 we go to great lengths to ensure our respective BOP adjustments offer a fair, rewarding and even playing field across the many cars currently available in the GT3 category of the simulation. Using a mix of physics data, performance telemetry and of course countless laps on the track by a number of drivers of different skill levels, we aim to apply performance BoP to each of the 13 GT3 cars that allows the player to have a fair and reasonable chance to mix it at the front of the field in any given car – just like in real life!
